I'm trying to use a function as a parameter in (duh) another function.
The param function is a callback.
I've got another function in the same class which matches the required format:
I want to use deadCallback as a default for the param so the function myFunc doesn't *require* a callback param.
If I leave the code: = self.deadCallback out the app compiles with no problem.
If I include it I get a compile time error:
"value of type (myClass) -> () -> (myClass) has no member deadCallback"
What am I doing wrong?
Can I do this?
If so, how?
class myClass {
func myFunc(_ url: String, callback: @escaping (_ resp: String) -> () = self.deadCallback) {
//do something that might make a string
var myStr? = "blah blah blah" //this may be nil which is perfectly acceptable
if(myStr != nil) {
callback(myStr!)
}
}
func deadCallback(_ resp: String) {
return
}
}
